LEWIS S. HOYT AND B. B. BEERS, OF NEW FAIRFIELD, CONNECTICUT.

BIT-STOCK AND WRENCH.

Specicaton of Letters Patent No. 24,807, dated July 19, 1859.

To all whom 'it may concern:

Be it known that we, LEWIS S. I-IoY'r and BENJAMIN BRUNsoN BEERS, bothof New Fairfield, in the county of Fairfield and State of Connecticut,have invented a new and useful IVimble or Bit-Stock Wrench; and we dohereby declare that the same is described and represented in thefollowing specification and drawings.

To enable others skilled in the art to make and use our invention wewill proceed to describe its construction and operation referring to thedrawings in which the same letters indicate like parts in each of thefigures.

Figure l, is a plan or side elevation. Fig. 2, is a view of its edge.Fig. 3, is an end view looking into the jaws. Fig. 4, is a side, andFig. 5, an end view of the block fitted to the jaws with a socketadapted to the shanks of common bits.

'Ihe nature of our invention consists in providing a wimble or bitstockwith one permanent, and one movable and adjustable jaw, the latter beingreadily adjusted to turn-nuts and screws of differentsizes with thegreatest facility, and in a block containing a socket adapted to receiveand-hold common bits, and fitted to the permanent or movable jaw orboth. Lastly in arranging a screw so as to fasten the block onto the jawand a bit in the socket at the same time.

In the acconlpanying drawings A, is a wimble or bitstock made in theform shown in the drawing, or in such other form as will answer thepurpose, with a head or knob B, fitted to turn freely as the wimble isworked or operated. The opposite end of the wimble from the knob B,terminates in a permanent jaw C, made in the form shown in the drawingto act in connection with the movable or vibrating jaw D, to turn nutsscrews bolts etc. The shanks of the aws C, and D, are hinged togetherwith a rule joint at E, and fastened by the screw bolt F, so that thejaw D, can vibrate freely and be adjusted to suit, the nut or bolt to beturned; and when so adjusted, it is held by the traversing strap G,which is fitted to traverse on the Shanks of the aws C, and D, and holdthem in the position desired, by placing the ends of the strap in thedifferent scores H, H, in the shanks of thejaws C, and D, the vibratingjaw D, being pressed from the permanent jaw, and against the strap G, bythe C spring I, shown in dotted lines in Fig. l. This spring I, isarranged in a cavity in the joint E, one end being fastened to thepermanent part of the hinge and the other to the moving part, so as topress the shank of the jaw D, against the strap G, as above mentioned;and whenever it is desirable to adjust the jaws, they may be pressedtogether and the strap moved, and placed in such position as will holdthe jaws as desired. The projection or knob J, on the jaw prevents thejaws from slipping to far onto the bolt or nut to be turned. The stra-pG, is made in the form shown in the drawing and the slot in it is madewidest in the middle so as to afford room for the Shanks of the jaws toturn when putting them into or taking them out of the strap.

When this wrench can be applied to the nut or bolt to be turnedperpendicularly, it can be used with greater facility and despatch thanany wrench made before the date of our invention; and where there is notsufficient room or space to apply it perpendicularly, it may be appliedhorizontally or at right angles to the bolt or nut to be turned as theknob or stop J, on the jaw C, prevents it from slipping too far onto thehead of the bolt to be turned or below it, which makes it far superiorto any other wrench. The strap G, may have a thumb screw fitted to oneend to adjust the jaws and clamp and hold a nut or bolt. The block K, isfitted to slip onto the jaw D, and has a socket L, in it adapted to theShanks of common bits; so that by applying the block to the jaw and abit to the socket L, in the block, it may be used with the same facilityfor boring, that it is for turning bolts or nuts. The screw N, isinserted in the block K so that one side of its point enters a score inthe block or stop J, the other side of its point projects into thesocket L so as to enter a score in the shank of the bit, so that thescrew N, fastens the block K, onto the jaw C, and the bit in the socketL, at the same time. This is novel, and a great advantage andimprovement.

We believe we have described and represented our wimble or bitstockwrench so as Vto enable any person skilled in the art to 2. We claim theblock K, or its equivalent the bit in the socketrL, at the same timesub- Wth a socket adapted to receive ald hold stantially as described.the Shanks of common bits' and tte to the 4 permanent or movable j aw7or bolt; so as to LEWIS S HOYT 5 hold the block and bits substantiallyas de- BENJAMIN B' BEERS scribed. Witnesses 3. We also claim the screwN, so arranged MARSHALL TREADWELL, as to fasten the block onto the jawC, and GEROME CHASE.
